I just wanted to say a big thank you to the jboss team for their work on the domain feature shipped with jboss 7. It is really easy to get going and the CLI makes management of it really straight forward. This domain feature will completely change they way we manage our applications (which currently span over multiple physical machines - http://community.jboss.org/wiki/ConfiguringMultipleInstanceOfJBossWithSpring) and add HUGE amounts of value to our lives.
